MikroTik CRS125-24G-1S-2HnD-IN Cloud Router Switch, 24x Gigabit Ports, 1x SFP, Built-in Wireless AP, Layer 3 Smart Switch

When building a modern business network, finding a single device that combines switching, routing, and wireless capabilities can save cost, space, and complexity. The MikroTik CRS125-24G-1S-2HnD-IN Cloud Router Switch is designed precisely for this purpose. This MikroTik Switch is a versatile piece of hardware that allows businesses to manage wired and wireless traffic in one integrated solution, without having to purchase separate routers, switches, and access points.

The CRS125-24G-1S-2HnD-IN is especially popular among small to medium-sized businesses, branch offices, and IT administrators who want enterprise-grade control in a compact, affordable device. With 24 Gigabit Ethernet ports, a dedicated SFP cage for fiber connectivity, and a built-in 2.4 GHz wireless access point, this device provides an all-in-one platform that is simple to deploy yet powerful enough to handle complex Layer 3 routing tasks.

Detailed Product Overview : MikroTik CRS125-24G-1S-2HnD-IN Cloud Router Switch

The MikroTik CRS125-24G-1S-2HnD-IN Cloud Router Switch is part of MikroTik’s CRS series, which merges fully manageable Layer 3 smart switch features with the powerful routing capability of RouterOS. This means network admins get full control over VLANs, firewalling, static routing, and even advanced configurations like MPLS, OSPF, and hotspot management.

Physically, the device comes in a compact desktop metal case with optional rack-mount kit, making it flexible for office or server room installations. Its fanless design means completely silent operation, which is critical in work environments where noise must be kept to a minimum. The CRS125-24G-1S-2HnD-IN also comes with an integrated 128 MB of RAM and a powerful Atheros AR9344 CPU running at 600 MHz, giving it enough processing power for routing, bridging, and wireless management simultaneously.

In addition to wired connectivity, the integrated dual-chain 2.4 GHz wireless radio supports 802.11b/g/n Wi-Fi standards and can be used as an access point or wireless client. This is particularly helpful for businesses that want to provide Wi-Fi coverage without purchasing separate APs, or for connecting to an upstream wireless provider.

Use Cases and Applications

The CRS125-24G-1S-2HnD-IN is ideal for small and mid-sized networks that need robust control over traffic flows. Businesses can deploy it as the core switch in an office to connect workstations, VoIP phones, IP cameras, and servers. The Layer 3 capabilities allow it to segment networks into VLANs, improving security and efficiency. Its routing functions can handle inter-VLAN routing, static routes, and even act as a firewall or DHCP server.

This model is also a great fit for branch offices that require a single box solution: it acts as the internet router, switch, and Wi-Fi AP, simplifying network design and reducing equipment costs. In labs or training centers, the built-in wireless AP can provide internet access to wireless devices while the Gigabit ports handle wired PCs.

Ports and Connectivity

The CRS125-24G-1S-2HnD-IN is equipped with 24 Gigabit Ethernet ports, which ensures high-speed connectivity for multiple devices simultaneously. This makes it perfect for environments where large data transfers, file sharing, and IP surveillance traffic are common.

Additionally, there is one SFP cage that supports a variety of SFP modules, allowing network admins to connect the switch to a fiber backbone or long-distance uplink. The wireless interface adds flexibility, letting administrators create hybrid wired-wireless networks or provide backup connectivity.

Practical Network Management for IT Teams

One of the biggest advantages of the CRS125-24G-1S-2HnD-IN is its RouterOS software. Administrators can configure the device via a user-friendly web interface, Winbox GUI, or full command-line access. This makes it easy to manage VLANs, set up firewall rules, monitor traffic, and even schedule automated tasks.

Its monitoring tools include real-time traffic graphs, interface statistics, and SNMP support for integration with network monitoring systems. This level of visibility is invaluable for IT teams that want to proactively manage network health.

Power Efficiency and Reliability

This device is built with efficiency in mind. Its fanless design reduces power consumption and noise, while passive cooling ensures long-term reliability. It can be powered via a standard DC jack or through passive PoE input, giving administrators flexibility in deployment, especially where traditional power sources are limited.

Comparison with Similar MikroTik Devices

This comparison shows that the CRS125-24G-1S-2HnD-IN is unique because of its built-in wireless AP, which is absent in most other CRS models.
